board: st: common: add uclass_get_device_by_driver()'s return value check

Browse Source 
class_get_device_by_driver()'s return value is not checked, in case of BSEC
driver is not probed, dev is not set and used just after as parameter of
misc_read() which leads to a Synchronous Abort.

Add uclass_get_device_by_driver()'s return value check to fix it.
